“…Furthermore, Zhang and Bellaloui (2012) stated that temperature and rainfall as essential factors affecting soybean seed shattering. Another study revealed that pod wall thickness as a determinant factor of soybean resistance to pod shattering (Tiwari and Bhatia 1995;Kuai et al 2016). …”

Abstract. Krisnawati A, Adie MM. 2017. Characterization and performance of agronomic characters of soybean genotypes resistant to pod shattering. Biodiversitas 18: 1158Biodiversitas 18: -1164. Pod shattering is one of the major obstacles of soybean cultivation in Indonesia's tropical climate. A total of 24 soybean genotypes, including Anjasmoro (check variety for pod-shatter resistant), Argomulyo and Grobogan (susceptible to pod shattering). The field experiment was conducted in Banyuwangi (East Java, Indonesia) during the dry season II 2016. The experimental design was randomized block, consisted of 24 soybean genotypes as sample trait with four replications. Pods from six random plants at physiological maturity (R8) were detached for pod shattering evaluation. The pod shattering evaluation was conducted in Laboratory of Plant Breeding, Indonesian Legumes and Tuber Crops Research Institutes (Malang, Indonesia) by using oven method and ambient temperature method. The classification of shattering resistance was according to Bailey et al. (1997) and Mohammed (2010), i.e. resistant (0-10% shattered pods), intermediate (11-70 % shattered pods) and susceptible (71-100% shattered pods). The average shattered pods of 24 genotypes by oven method reached 42.67%, higher than those of ambient method (21.81%). Six soybean genotypes showed consistently resistant to pod shattering based on oven as well as ambient method. Pods position at lower part was more susceptible to pod shattering than those at middle and upper part. The limit of pod shattering was ranging from two to 38 days. Genotype of G511H/Anjs/Anjs-1-2 which characterized by pod shatter resistant, produced high yield, and large seed size, was potentially developed at the tropical area, such as Indonesia.

“…In Brassica, taller and sturdier plants tend to produce more shatter-resistance pods [122]. Shatter-resistance in Brassica was also found to be affected by the size and weight of pod structures such as valves, beak, and septum [122,141]. Another study found a positive correlation between shatter-resistance and the main vascular bundle size in Brassica [135].…”

Pod Shattering: A Homologous Series of Variation Underlying Domestication and an Avenue for Crop Improvement

In wild habitats, fruit dehiscence is a critical strategy for seed dispersal; however, in cultivated crops it is one of the major sources of yield loss. Therefore, indehiscence of fruits, pods, etc., was likely to be one of the first traits strongly selected in crop domestication. Even with the historical selection against dehiscence in early domesticates, it is a trait still targeted in many breeding programs, particularly in minor or underutilized crops. Here, we review dehiscence in pulse (grain legume) crops, which are of growing importance as a source of protein in human and livestock diets, and which have received less attention than cereal crops and the model plant Arabidopsis thaliana. We specifically focus on the (i) history of indehiscence in domestication across legumes, (ii) structures and the mechanisms involved in shattering, (iii) the molecular pathways underlying this important trait, (iv) an overview of the extent of crop losses due to shattering, and the effects of environmental factors on shattering, and, (v) efforts to reduce shattering in crops. While our focus is mainly pulse crops, we also included comparisons to crucifers and cereals because there is extensive research on shattering in these taxa.
